Perkins original Perkins 127-8222 Common Rail Injector 127-8216 127-8218 127-8213 Replacement for Caterpillar 3114 3126 new injector original new injector

Engineered as a direct OEM-type replacement, the Perkins 3116 fuel injector 127-8222 1278222 is built for Perkins 3116 diesel engines, with verified fitment also extending to Perkins 3114 and 3126 configurations that use the same mechanical unit injector platform. The part carries authorized cross references including 107-1230, 1071230, 0R-8461, 0R8461, OR8461, 4P-1731, 4P1731, 0R-3580, 0R3580, and CA1278222, giving buyers wide coverage against common part-book listings. Heavy-duty internal components support precise fuel delivery and stable atomization, helping maintain combustion efficiency, power output, and reduced abnormal smoke when properly installed and calibrated.

This injector is commonly specified for Perkins 322L, 325, and 325L excavators, 950F, 950F II, and 960F wheel loaders, 613C and 613C II wheel tractor scrapers, Challenger 35/45/55 agricultural tractors, and combine models 460, 465, and 470. It serves construction, mining, agricultural, power generation, marine support, fleet maintenance, engine rebuild, and aftermarket parts distribution channels. Each unit is quality-tested for compatibility, dimensional accuracy, and spray pattern consistency prior to shipment.

Routine maintenance should follow standard mechanical injection practice: use clean diesel, service the fuel filter at scheduled intervals, drain the water separator, and keep the fuel tank free from contamination. Inspect the injector for external leakage, carbon buildup, and nozzle wear. Diagnose hard starting, rough idle, misfire, black or white smoke, diesel knock, power loss, and elevated fuel consumption against injector atomization and flow performance. Replace injectors as a complete matched set when cylinder balance cannot be restored, and store unused units in sealed, dry, anti-rust packaging to preserve shelf life.
